Define Ignition Temperature?

Ignition temperature, also known as the autoignition temperature or kindling point, refers to the minimum temperature at which a substance or material will spontaneously ignite or catch fire in the presence of an oxidizing agent, such as air or oxygen, without the need for an external ignition source like a flame or spark. This temperature is specific to each substance and is influenced by factors such as the substance's chemical composition, physical properties, and surrounding conditions.

When the temperature of a substance reaches or surpasses its ignition temperature, the molecules within the material become energized to a point where they can initiate and sustain a self-sustaining combustion reaction. This can lead to a fire or explosion, depending on the nature of the substance and the environment in which it is located. Ignition temperature is an important consideration in fire safety and industrial processes, as understanding the ignition characteristics of materials is crucial for preventing and managing potential fire hazards.
